IMPROVEMENT IN MACH-INES FOR MAKING PAPER BOXES.

Specification forming part of Letters Patent No. 48,490, (lated June 27, 18651.

To all whom it may concern: Be it known that I, T. C. LUTHER, ot' Waterbury, in the county of New Haven and State of Connecticut, have invented a new and Improved Machine for Manufacturing Paper Boxes; and I do hereby declare that the following is a` full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure l -is a side sectional view of my invention, taken in the line m x, I"ig. 2; Fig. 2, a front elevation of the saine. p

Similar letters ot' reference indicate like parts.

This invention relates to a new and useful machine for facilitating the manufacture of paper boxes; and it consists in cmbininga series of cutters with a pair of pressure-rollers, on oneof.which the paper cylinder is formed, all being arranged in such av manner that the cylinders 1may be formed and cut into pieces ot' requisite length at one operation.

The invention is designed for manufacturing small paper boxes, such as are used for holding percussion-caps, Sac., andere of circular form.

Hithexto the bodies or main portions of these boxes have been formed by rolling paper around a 'cylinder so as to form a' tube ot' requisite thickness, and then cutting said tube intopieces of requisite length after being withdrawn from the cylinder, two separate operations being required to peform the work which by my improvement is done at one operation.

A represents a frame, in which a roller, B, is fitted and works in fixed bearings, and C is a roller smallerthan B, having a diameter y corresponding to that designed for the interior of the papercylinders or tubes to be formed upon it. The roller C does not work in fixed bearings, and is therefore movable, so that the paper, when wound upon it, maybe pressed against the roller B. The roller C is provided with a crank, D, at one end for the purpose of turning it.

'E represents a shaft, which is fitted in a frame, F, the latter being placed loosely on a shaft, G, in the frame A. The shaft E has a series of circular cutters, H, upon it, which are secured at suitable distances apart by placing circular blocks or washers a between them. The shaft E is allowed to Arotate freely in the frame F, and by depressing the end of frame4 F which is opposite to the end in which the shaft E is placed the cutters may be brought in contact with the paper cylinder on the roller C, as shown in red in Fig. l.

AThe operation is as follows: The paper is wound upon the roller C, and com pressed While being Wound upon it by pressing it against the roller B, the end of the paperbeing pasted to prevent the tube or cylinder from unwinding. After the paper cylinder or tube is thus formed, which is the com mon-Inode now practiced, the cutters H are pressed against it and the cylinder or tube will be cut into pieces of a length corresponding to the spaces between the cutters, which is the length required forI the boxes. Thus it will be seen that by this simple means I ain enabled to form the paper cylinders or tubes and cut theln into piecespf the required length at one and the same operation.

I do not claim the rollers B C separately, for they have been previously used 5 but I claim as new and desire to secure by Letters Patent- The cutters H, in combination with the rollers B C, arranged to operate in the manner substantially as and for the purpose specified.

T. C. LUTHER.
